Overview

Elevate your FastAPI project from a functional prototype to a production-grade service with this advanced codelab. This guide focuses on the critical features needed for real-world applications. You will learn to structure scalable projects using APIRouter, ensuring your codebase remains clean and manageable as it grows. We'll implement robust security by adding JWT-based authentication with OAuth2 to protect your endpoints, and you'll master FastAPI's dependency injection system for writing cleaner, more maintainable code. To maximize performance, you'll explore how to leverage asynchronous operations with async and await. Finally, you'll learn to ensure your API is reliable and bug-free by writing effective tests with pytest and TestClient. By the end, you will have a secure, scalable, and fully tested API blueprint ready for deployment.
